#GenerativeAI can make the process of generating alternative text faster. However, it's important to note that GenAI-generated alt text can contain errors, making human review and intervention essential to ensure accuracy and meaningfulness.

Let's do it!

1. Log into ChatGPT 4.0.

2. Upload an image and enter the following prompt:

"Act as an expert in web accessibility and write concise and meaningful alternative text for this image so that it can be described via a screen reader."

3. Assess the quality of the output and share this in the comments below.

For this challenge, I have generated the following alternative text for the image below.

Alternative Text: A black and white photograph of a farm field with two sections labeled. The left side is labeled 'Starved by lack of plant food,' showing sparse and unhealthy plants, while the right side is labeled 'Nourished on phosphate and lime,' showing healthier, more abundant growth. A person kneels in the field, tending to the plants.
